Ma nā wahi eli ʻana o ke Komohana ʻAmelika, mai nā ʻano granite o Colorado a i nā pōhaku paʻakikī waiwai hao o Minnesota, ʻo ke kūpaʻa ʻana o nā mea hana ʻoki e kuhikuhi pololei i ka pono o ka eli ʻana a me ka palekana hana. Ua makemake nui ʻia nā mea ʻoki PDC no ko lākou ʻoi, akā i ka wā e kū nei i nā papa palupalu-paʻakikī a me nā hopena pōhaku koke, ʻike ka nui o nā mea hana ʻeli iā lākou iho e hakakā nei me nā hemahema pinepine o nā mea hana. Ma hope o 96 mau hola o ka hoʻāʻo ʻana ma ka ʻaoʻao ma kahi lua pōhaku paʻakikī o Wyoming, ʻo kaNiho hui ʻāpana daimanaua kū i waho me kona mau pono kūkulu kūikawā, e hōʻike ana i ke kūpaʻa hopena kupaianaha e kūlike ana me nā hiʻohiʻona koi nui o nā hana mining o ʻAmelika Hui Pū ʻIa.
Pōmaikaʻi Kūkulu: Pehea e hoʻolaha ai ka niho hui Diamond taper i ka ikaika hopena
ʻO ke kī i ke kūpaʻa ʻana i ka hopena e waiho ana i ka hoʻolālā kūkulu, a ʻo ka ʻokoʻa ma waena o ka niho hui Diamond taper a me nā mea ʻoki PDC he mea kupaianaha. ʻO ka maʻamau, hōʻike nā mea ʻoki PDC i kahi ʻili pālahalaha a ʻōniʻoniʻo iki paha; i ka wā e kuʻi ai i nā ʻāpana pōhaku paʻakikī a i ʻole nā uaua quartz, kau ka ikaika hopena ma kahi liʻiliʻi, e maʻalahi ai ke kumu o ka ʻili ʻana o ka papa daimana a i ʻole ke kino ʻoki e haki.
ʻO ka toot hui taper daimanaʻO h, ma ke ʻano ʻē aʻe, lawe i kahi hoʻolālā hoʻonohonoho conical me kahi ʻili i hoʻololi maʻalahi ʻia. Hana kēia ʻano e like me ka "diffuser force" - ke kuʻi ʻia me ka pōhaku paʻakikī, ua hoʻolaha like ʻia ka ikaika hopena ma ka ʻili conical ma kahi o ka nānā ʻana i hoʻokahi kiko. I ka wā o ka hoʻāʻo ʻana, ua hoʻohālike mākou i ka hopena o ka ʻili quartz 3.1g/cm³ ma nā mea hana ʻelua: ua hōʻike nā mea ʻoki PDC i nā micro-cracks ma hope o 3,000 mau hopena, ʻoiai ʻo ka niho hui Diamond taper i noho paʻa ma hope o 6,000 mau hopena. Kōkua pū ka piko conical i ka nahu koke ʻana o ka niho i ka pōhaku, e hōʻemi ana i ka "hopena rebound" i hoʻokumu ʻia e ka paheʻe ʻana, he pilikia maʻamau me nā mea ʻoki PDC i nā ʻano pōhaku i ʻoki ʻia.
Nā Hualoaʻa Hoʻāʻo Kahua: ʻĀlohilohi ka niho hui Diamond taper i nā Kūlana ʻino
No ke kope ʻana i nā wahi eli maoli ai, ua hoʻokomo mākou i nā mea ʻoki niho Diamond taper a me PDC ma ka roaheader hoʻokahi, e hana mau ana i loko o kahi lua me nā papa shale a me granite - he hiʻohiʻona maʻamau i nā lua metala US. Ua maopopo nā hopena:
Pono nā mea ʻoki PDC e hoʻololi i kēlā me kēia 5 hola, me 25% o lākou e hōʻike ana i ka chipping maopopo a me ka hohonu ʻaʻahu awelika o 0.5mm. I kēia manawa, ua holo ka niho hui Diamond taper no 14 mau hola pololei me ka 0.18mm wale nō a ʻaʻohe chipping a ʻili paha. I ka hoʻāʻo hopena koke (e hoʻohālike ana i ke kuʻi ʻana me nā poloka pōhaku huna), ua loaʻa i nā mea ʻoki PDC kahi helu hāʻule o 18%, ʻoiaiNiho hui ʻāpana daimanaua mālama ʻia kahi pae kūpaʻa 100%. He mea koʻikoʻi kēia ʻokoʻa hana no nā mines US, kahi e hiki ai ke uku ʻia he mau tausani kālā i kēlā me kēia hola no ka manawa hana ʻole ma muli o ka hoʻololi ʻana i nā mea hana.
Waiwai Hana: Hoʻemi ka niho hui Diamond taper i nā kumukūʻai no nā lua ʻeli US
No nā ʻoihana mining US, ʻo ke kū'ē ʻana i ka hopena e unuhi hope loa i ka mālama kālā. Ua hoʻohana mua kahi lua gula ma Nevada i nā mea ʻoki PDC, e pani ana i 4 mau seti i kēlā me kēia lā a loaʻa ke kumukūʻai o nā mea hana i kēlā me kēia lā he $3,200, me 2 mau hola o ka manawa hoʻomaha. Ma hope o ka hoʻololi ʻana i ka niho hui Diamond taper, ua hāʻule ke alapine hoʻololi i 1 set i kēlā me kēia 3 lā, ua emi ke kumukūʻai o nā mea hana i kēlā me kēia lā i $800, a ua hōʻemi ʻia ka manawa hoʻomaha e 90%.
Ua hōʻike kekahi lua lanahu ʻē aʻe ma Pennsylvania ua ʻae ka pale ʻana o ka niho hui Diamond taper iā ia e lawelawe i nā hoʻokomo pōhaku paʻakikī i loko o nā ʻūpā lanahu me ka ʻole o nā kū pinepine, e hoʻonui ana i ka hana i kēlā me kēia lā ma 15%. ʻO kēia pono "paʻa kiʻekiʻe, hoʻololi haʻahaʻa" e hana ai.ʻO ka toot hui taper daimanahe koho kūpono i ke kumukūʻai no nā lua mina US e kū nei i ke piʻi ʻana o nā kumukūʻai hana a me nā kūlana ʻekele honua koi.
No nā kikoʻī hou aku maNiho hui ʻāpana daimanaa i ʻole e kūkākūkā i ka hoʻopilikino ʻana no nā hiʻohiʻona mining US, e hoʻokaʻaʻike:

E Pili Ana i ka Mea Kākau: ʻO Jake Thompson, he kamaʻāina no Montana, USA, he 12 mau makahiki o ka ʻike ma ke ʻano he ʻenekinia hoʻāʻo mea hana mining. Ua hana ʻo ia me nā mines US he 30 ma nā Rockies, Appalachians, a me Midwest, e loea ana i ka hoʻāʻo ʻana i ka hana kahua a me ke koho ʻana i nā mea hana ʻoki no ka pōhaku paʻakikī a me nā ʻano paʻakikī. Hoʻokumu ʻia kāna ʻike ma ka ʻike lima, e kōkua ana i nā mines e hoʻonui i ka pono a hoʻemi i nā kumukūʻai ma o nā hoʻonā mea hana kūpono.
